Abstract

In the process of CNC turning, accuracy and surface quality are key indicators for evaluating its effectiveness. This paper explores strategies to optimize the precision and surface quality of CNC turning through empirical research methods. By reasonably adjusting parameters such as cutting speed, feed rate, and depth of cut, and combining them with target optimization algorithms, specific operational solutions have been successfully found to achieve coordinated optimization of precision and surface quality. The study finds that by reducing the cutting speed, increasing the feed rate, and selecting an appropriate depth of cut, it is possible to significantly improve the dimensional accuracy and surface roughness of turned parts while maintaining processing efficiency. Furthermore, using optimization algorithms can further enhance processing accuracy, with the improvement in surface quality reaching up to 30%. This research has significant guiding significance for improving the efficiency and quality of CNC turning processes and provides theoretical references for optimizing turning parameters in practical production.
